The municipality of Broomfield was incorporated in 1961 in the southeastern corner of Boulder County. While it is unsure how it received its name, most researchers guess it is from the broomcorn grown in the area, a tall sorghum that farmers sold for use as brooms and whisk brooms. Over the next three decades, the city grew through annexations, many of which crossed the county line into four adjacent counties: Adams, Boulder, Jefferson and Weld. In the 1990s, city leaders began to push for the creation of a separate county to avoid the inefficiencies of dealing with four separate court districts, four different county seats, and four separate county sales tax bases. It also had longstanding political differences with Boulder County [ clarification needed ] which impelled it to separate.
